Mobile phone tracking is a technique that uses various technologies to determine the geographical location of a mobile device[1]. This tracking can be done through network-based technologie[2], which uses the mobile network infrastructure to determine the device’s location. Handset-based technology uses software installed on the device and GPS signals to pinpoint location. SIM-based technology uses raw radio measurements from the device’s SIM card, while Wi-Fi-based technology uses Wi-Fi data for location identification. A hybrid positioning system can combine these methods for increased accuracy. However, the use of mobile phone tracking raises significant vie privée[3] and legal concerns. Many countries, particularly in Europe, have strict laws protecting location data and the privacy of individuals. Despite the benefits of mobile phone tracking, such as aiding in navigation or emergency services, it’s important for users to be aware of potential privacy implications.

Définitions des termes
1. mobile device. Mobile devices are dynamic tools that offer a broad spectrum of functionalities and applications across various industries. Defined by their portability, these devices range in size from pocket-friendly gadgets to larger equipment. Their physical aspects, including dimension and weight, allow for easy attachment to different host devices and mobility across diverse settings. Despite their portability, wireless connectivity is not a prerequisite. Mobile devices can access networks through both wired and wireless connections, and some even operate without internet connectivity. They are integral in numerous industries, providing solutions for field management, real-time conferencing, asset tracking, and more. However, their application in sectors such as gambling and adult entertainment has prompted regulatory scrutiny. Additionally, they are increasingly used in military operations for training and educational purposes.
2. technologie. La technologie, dérivée des mots grecs signifiant artisanat et connaissance, est un terme général qui désigne les outils, les machines et les systèmes mis au point par l'homme pour résoudre des problèmes ou atteindre des objectifs. Née avec des outils primitifs comme les haches de pierre et la découverte du feu, la technologie a évolué de manière significative tout au long de l'histoire de l'humanité. Elle a joué un rôle déterminant à différentes époques, depuis l'invention de la roue et des systèmes d'irrigation avancés dans les civilisations anciennes jusqu'à la naissance des universités et de la presse à imprimer au cours des périodes médiévale et de la Renaissance. La révolution industrielle du XVIIIe siècle a marqué un tournant important dans la production de masse et l'innovation, donnant naissance aux technologies modernes telles que l'électricité, l'automobile et les plates-formes de communication numérique. Aujourd'hui, la technologie fait partie intégrante de divers aspects de la vie et de la société, stimulant la croissance économique et les changements sociétaux, tout en suscitant des préoccupations en matière de sécurité, de respect de la vie privée et d'incidences sur l'environnement. L'avenir de la technologie devrait apporter encore plus de progrès, avec l'essor de l'intelligence artificielle qui devrait avoir des implications significatives sur le marché du travail.

Traçage des téléphones portables is a process for identifying the location of a mobile phone, whether stationary or moving. Localization may be affected by a number of technologies, such as the multilateration of radio signals between (several) cell towers de la network and the phone or by simply using GNSS. To locate a mobile phone using multilateration of mobile radio signals, the phone must emit at least the idle signal to contact nearby antenna towers and does not require an active call. The Global System for Mobile Communications (GSM) is based on the phone's signal strength to nearby antenna masts.
